Abstract: When modelling, analysing, and simulating mobile radio channels, it is generally assumed that the speed of the mobile station (MS) is constant. In practice, however, the mobile speed varies ...

Radio frequency (RF) spectrogram analysis for indoor human activity recognition has traditionally relied on supervised learning with larger labeled datasets. We present a novel framework that employs ...

Bengalese finch song analysis is essential in bioacoustics for studying avian communication. Spectrograms visually represent audio signals, displaying frequency content over time. When a finch sings, ...
